Oxygen toxicity during artificial ventilation.
Repeated pulmonary collapse and changes suggestive of a severe alveolar-capillary diffusion defect were observed over a period of 20 days in a patient who was receiving artificial ventilation because of status epilepticus. Profound cyanosis followed attempts to discontinue assisted ventilation. The Bird Mark 8 respirator employed was found to be delivering approximately 90% oxygen on the air-mi...
متن کاملAssisted ventilation using cuirass respirators.
The effects of cuirass-assisted ventilation have been studied in 25 subjects with chest wall disease. Cuirass respirators increase ventilation in proportion to the peak negative pressure within the cuirass shell and the respiratory rate. Positive pressure applied during expiration produces little additional ventilation. During cuirass-assisted ventilation end-expiratory volume increases, arteri...
متن کاملPressure-controlled ventilation and intrabronchial pressure during one-lung ventilation.
BACKGROUND Pressure-controlled ventilation (PCV) has been suggested to reduce peak airway pressure (P(peak)) and intrapulmonary shunt during one-lung ventilation (OLV) when compared with volume-controlled ventilation (VCV). At the same tidal volume (V(T)), the apparent difference in P(peak) is mainly related to the presence of a double-lumen tracheal tube. We tested the hypothesis that the decr...
متن کاملContinuous positive pressure ventilation and oxygen delivery.
The effects of intermittent and continuous positive pressure were studied in mechanically ventilated healthy dogs. No statistically significant changes were produced in oxygen tension, carbon dioxide tension, alveolar-arterial gradients or shunts by continuous positive pressure. It did produce a significant reduction in cardiac output and total oxygen delivery which was reversed by the reintrod...
متن کاملDeterminants of Fi,O2 with oxygen supplementation during noninvasive two-level positive pressure ventilation.
To maintain arterial oxygen saturation (Sa,O2) above 90% in patients with acute respiratory failure, oxygen (O2) is often added to the circuit of two-level noninvasive positive pressure ventilation (NPPV). However, the final inspiratory oxygen fraction (Fi,O2) is not known. To clarify this issue, the effect of different inspiratory positive airway pressures (IPAP) of the oxygen tubing connectio...
